[0008] The bottom buffer box includes a bottom groove for accommodating the inverter body and a waterproof cover insertion groove for inserting the wiring waterproof cover.

[0009] The top buffer box includes a top cavity for accommodating the bottom groove to receive the inverter body, and a waterproof cover internal channel for accommodating the waterproof cover insertion groove. The top of the top buffer box is provided with a limiting receiving chamber for limiting the mounting of the wall bracket.

[0010] Preferably, the buffer box includes four L-shaped corner guards with an L-shaped cross section, and the four corner ends of the bottom buffer box and the four corner ends of the top buffer box are respectively provided with plug-in grooves for cooperating with the L-shaped corner guards.

[0011] Preferably, the buffer box includes at least one V-shaped structural frame with a V-shaped cross-section, and the bottom buffer box body and the top buffer box body are respectively provided with V-shaped grooves for cooperating with the V-shaped structural frame.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0030] This utility model provides a photovoltaic inverter packaging box, such as Figures 1 to 4 As shown, the device for housing the inverter body 100, wall mount 200, and wiring waterproof cover 300 includes a cardboard box body 1 and a buffer box 2 built into the cardboard box body 1.

[0031] like Figures 1 to 4 As shown, the buffer box 2 includes a bottom buffer box 3 and a top buffer box 4 that are spliced ​​together.

[0032] The bottom buffer box 3 includes a bottom groove 31 for accommodating the inverter body and a waterproof cover plug groove 32 for plugging in the waterproof cover.

[0033] The top buffer box 4 includes a top cavity 41 for accommodating the bottom groove to house the inverter body, a waterproof cover internal channel 42 for accommodating the waterproof cover insertion slot, and a limiting receiving chamber 43 at the top of the top buffer box 4 for limiting the mounting wall bracket.

[0034] Detailed implementation process and principle explanation:

[0035] During the packaging process, the bottom buffer box 3 is placed at the bottom of the carton body 1, and then the inverter body 100 is placed in the bottom groove 31. The wiring waterproof cover 300 is then inserted into the waterproof cover insertion groove 32.

[0036] Then, the top buffer box 4 is placed on the bottom buffer box 3, so that the top cavity 41 covers the inverter body 100 and the exposed part of the wiring waterproof cover 300 is contained in the waterproof cover's built-in channel 42. Finally, the wall mount 200 is inserted into the limiting and receiving cavity 43 and then packed into a carton, thus achieving overall packaging.

[0037] In one specific embodiment, the buffer box 2 includes four L-shaped corner guards 5 with an L-shaped cross section, and the four corner ends of the bottom buffer box and the four corner ends of the top buffer box are respectively provided with plug-in grooves 6 for cooperating with the L-shaped corner guards.

[0038] Specifically, after the bottom buffer box 3 is placed in place, four L-shaped corner guards 5 are inserted into the insertion slots 6 on it, with some of them exposed. When the top buffer box 3 is covered, the insertion slots 6 cooperate with each other to achieve a guiding effect for the cover. In addition, the L-shaped corner guards 5 can play a supporting role, making the buffer box less prone to deformation, and the overall pressure resistance and deformation resistance of the enclosure are significantly improved.

[0039] In one specific embodiment, the buffer box 2 includes at least one V-shaped structural frame 7 with a V-shaped cross section, and the bottom buffer box body and the top buffer box body are respectively provided with V-shaped grooves 8 for cooperating with the V-shaped structural frame.

[0040] This further enhances the structural strength and strengthens the local support performance.

[0041] In one specific embodiment, the top buffer box 4 includes two spliced ​​top boxes 40, and V-shaped grooves are provided at both ends of the splicing seam of the two spliced ​​top boxes.

[0042] The splicing structure of the top box 40 is adopted to meet the tolerance requirements of the box cover. In particular, it can first take into account the alignment and cooperation of the internal channel 42 of the waterproof cover, and then make positional adjustment with the inverter body 100. This makes the packing more convenient and efficient.

[0043] In one specific embodiment, the bottom wall of the arbitrarily assembled top box 40 and the bottom buffer box body are provided with a handle clearance groove 400.

[0044] This makes it so convenient to move the splicing top box 40 when unpacking.

[0045] In one specific embodiment, the top of the top buffer box 4 is provided with several accessory pack placement slots 44.

[0046] It is convenient to carry accessories such as pins and nuts in the accessory bag.

[0047] In one specific embodiment, the bottom wall of the limiting receiving chamber 43 is provided with two opposing limiting grooves 430.

[0048] This satisfies the limiting and locking requirements of the wall mount 200. The wall mount 200 is generally I-shaped with bars at both ends. The limiting groove 430 satisfies the embedded limiting and fixing requirements of the bars.

[0049] In one specific embodiment, two inverter lifting ports 30 are provided on the outer peripheral wall of the bottom groove of the bottom buffer box 3.

[0050] The inverter lifting port 30 meets the lifting requirements for moving the inverter during unpacking.

[0051] In one specific embodiment, the bottom of the bottom buffer box 3 is provided with an adhesive layer 33 for bonding to the carton body.

[0052] The adhesive layer 33 can firmly bond the bottom buffer box 3 to the carton body, thus effectively preventing bouncing during transportation, providing better cushioning performance, and making the protection of the inverter more reliable and effective.

[0053] In one specific embodiment, the carton body 1 is provided with a carton lifting handle 10. This carton lifting handle 10 facilitates the handling of the carton after the inverter is mounted.

[0054] As described above, the photovoltaic inverter packaging box of this utility model meets the requirements for isolating and mounting the inverter body, wall mount, and waterproof wiring cover. It possesses high buffering performance and structural support, strong pressure resistance, and high deformation resistance, meeting stringent testing requirements such as packaging stacking pressure tests and drop tests. The overall design is compact and ingenious, featuring small size, high safety, and low cost.

[0055] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent in such process, method, article, or apparatus / device.

[0056] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
